花粉症的治疗有特异性和非特异性两类方法,前者包括避免致敏花粉和用特异性花粉变应原进行的免疫疗法;后者主要是应用药物控制症状,适用于致敏花粉种类单纯,发作期短的病例,或作为免疫疗法的辅助措施。花粉症是Ⅰ型变态反应病中应用免疫疗法效果最佳的病种之一。由于应用免疫疗法治疗花粉症可以防止季节性发怍,效果比较满意,故一向为变态反应学家所推崇。但是,此种方法的一个重要缺点是治疗时间过长,需要反复进行注射,有些患者难以坚持。为了克服这个缺点,曾进行了一系列的努力来改进免疫治疗的方法。改革的途径主要有二:一是改良免疫治疗浸液的剂型,例如将花粉变应原制成类变应原、聚合变应原等,在保留制剂的免疫原性的条件下,降低其变应原性,以减少注射反应,从而可以增大注射剂量,缩短治疗时间;二是改进免疫治疗的操作方法, The treatment of hay fever, there are two kinds of specific and non-specific methods, the former includes to avoid sensitized pollen and specific pollen allergen immunotherapy; the latter is mainly the application of drug control symptoms, suitable for allergen pollen species simple, Short episodes, or as an adjunct to immunotherapy. Hay fever is one of the most effective types of immunotherapy in type I allergy. As the application of immunotherapy for treatment of hay fever can prevent seasonal hair loss, the effect is more satisfactory, it has always been highly recommended by allergic scientists. However, an important disadvantage of this method is the long treatment time, the need for repeated injections and the inability of some patients to persevere. To overcome this shortcoming, a series of efforts have been made to improve the immunotherapy approach. There are two main ways to reform: First, improve the immunosuppressive infusion formulations, such as the pollen allergen into allergens, polymerized allergens, etc., to retain the immunogenicity of the preparation under the conditions of its variable Should be in order to reduce the injection reaction, which can increase the injection dose, shorten the treatment time; the second is to improve the immunotherapy operation,
